Ian Rogers ca76fb67eb perf evlist: Improve default event for s390 ...

Frame pointer callchains are not supported on s390 and dwarf
callchains are only supported on software events.

Switch the default event from the hardware 'cycles' event to the
software 'cpu-clock' or 'task-clock' on s390 if callchains are
enabled. Move some of the target initialization earlier in builtin-top
and builtin-record, so it is ready for use by evlist__new_default.

If frame pointer callchains are requested on s390 show a
warning. Modify the '-g' option of `perf top` and `perf record` to
default to dwarf callchains on s390.
